I have tried using the Buckle analysis, and then *Imperfection command but it produced negligible amount of unevenness. The expected result is having the top nodes at different Y-coordinates.

I would really appreciate any help in this regard.

Have you seen the scale factor option at *Imperfection?

Yes, I have used 0.01 scale factor first (5% of the strut dia), then 0.05 scale factor (25% of strut dia). Nearly same results.

You are aware that the scale factor is related to the buckling mode?

Maybe what you want has to be done manually, since there is no buckling mode that creates unequal displacements at the top surface.
